Why retracted facts still poison your Agent's memory
go_kul_07 · reddit · 2026-09-02
A technical deep dive into a memory engine bug where retracted facts were still believed by the model due to a mere priority penalty (-0.3).
- Root Cause: Inconsistent definitions of "retracted" across subsystems caused leaks.
- Fix: Distinguished "evidence degrees" (ranking) from "acts of retraction" (withholding). Retracted items are now stripped from context.
- Compliance Trap: The fix couldn't hide retracted items from GDPR disclosure selectors to avoid under-disclosing.
- Open Problem: "Memory laundering"—old transcripts can re-insert deleted facts as new rows. Preventing this requires a "never believe" hash list, raising compliance questions.
